I found Albert Roggenbuck (could be the brother of Antonia?) and Emma Polkow married 1891 in Cook County, Ill. One Daughter is Helen Matilda born Oct. 1900 Chicago, Ill. She married 1919 H.H. Timm in North Star Twp, Brown Co, Mi.

** This is the same person!

The first name of Antonia´s father could be Peter or Albert, two different sources available!
